And it is certainly no match for the world’s greatest aquatic hunter — the killer whale. In the last few years, scientists have noted an ever-growing number of killer whales in Arctic waters in the summer months. More and more have been attracted to these hunting grounds by the growing expanse of open water. They attack the same prey as the polar bears: seals, narwhal, belugas and bowhead whales.

He will have access to 46 television stations for 13 hours every day. How will these images shape a child so isolated from commerce, materialism and celebrity? By Thomas Balmes.
